What happens when you manually run your cron entry? You might find you need to add ‘php’ in front of it, see: WeatherMap editor and php 8.1 : incompatibility? - #15 by Philip_Jewell

My guess is php-fpm is running as the web user (not librenms) this means it doesn’t have permission to write to that directory according to your original post.

Either amend the permissions, or set the the librenms php-fpm pool as described in the current documentation.

It was set according to the Librenms manual.

added
chown -R librenms:librenms /etc/php/8.1/fpm
chmod 775 /etc/php/8.1/fpm

drwxrwxr-x 4 librenms librenms 4096 Nov 2 14:25 fpm/

Still the same 404 not found

librenms should NOT own the php-fpm files.

Note that the Weathermap plugin has problems and might require manual intervention. It seems mostly unmaintained.
